Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

A series of viral social media posts drew attention to an old cosmological theory-that our universe began from a collision ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, ...

We'll cut right to the chase: This video of Stanford Professor Andrei Linde finding out about yesterday's big discovery of "smoking gun" evidence of cosmic inflation (the "first tremors of the big ...

Is the universe 'tuned' to support life, and ultimately us? Physicists Nemanja Kaloper and Alexander Westphal have proposed ways to test this Anthropic principle. (Image of deep star field from the ...

How did the universe begin? A compact NASA space telescope that uses less power than a refrigerator is poised to chip away at that large question. Called SPHEREx, and set for launch on a SpaceX Falcon ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

A team of scientists proposes a new model of cosmic inflation that reveals how gravity and quantum mechanics may be sufficient to explain how the structure of the cosmos came into being. A team of ...

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...
